Please help !!!Which of the following alcohols is now commonly being used as fuel additive?

methyl alcohol
ethyl alcohol
isopropyl alcohol
none of the above

Answers

Out of the following alcohols we can conclude the correct answer choice by going through our options, looking at their chemical formulas/structures and defining their usage.

 Ethyl alcohol (CH3CH2OH) :  Most commonly found in alcoholic beverages.

Isopropyl alcohol (C3H8O) : Is what is known as rubbing alcohol, most commonly used as a cleansing liquid.
 
Methyl alcohol (CH3OH) :  Is most  commonly used  as formaldehyde, jet fuel, and antifreeze.

So looking at our options we can conclude that the correct answer choice would be Methyl Alcohol because it is used as an additive in jet fuel.

Hope this helps! If you have any other questions or would like further explanation just let me know!  :)

What does it mean to discuss the concentration of a solution

Answers

When you are discussing the concentration of solution, you are discussing how many particles there are in a given amount of solvent. You are comparing. If there is more solute in a beaker of solvent, then it is highly concentrated. If there is less solute in a beaker of the same amount of solvent, then it is less concentrated or more dilute. The terms diluted and concentrated are related to each other. These words are used to compare certain solutions to each other, since there is nothing like numbers, these words are relative to one another.

What is the percentage of water to the nearest tenth in this compound? Ba(OH)2 * 8H2O

Answers

mass of water: 8 * 18 g = 144 g
mass of Ba(OH)2 = 171.3 g

total mass: 144 g + 171.3 g =  315.3 g

percentage of water: (144 g / 315.3 g) * 100% = 45.67%
